Background

Getting to know salted sunflower seeds in the shell

Salted sunflower seeds in the shell sit in the pantry staples section of our food guide. The USDA FoodKeeper database files them under the name “Sunflower seeds (roasted, salted, in shell)”. They fall into the lower-risk group, so storing them well is mostly about keeping quality rather than about safety. Best storage spot: it does not need the fridge; a dark, dry, cool cupboard suits it best.

Foods rich in fat, like butter, nuts, seeds, cooking oils and nut butters, don't support bacterial growth easily, so their main problem is rancidity rather than foodborne illness. Small amounts of rancid fat usually aren't harmful, but they taste bitter and stale. Storing these foods somewhere cool, dark and airtight slows rancidity; the fridge slows it even more.

What's happening

What makes salted sunflower seeds in the shell spoil

Heat, light and oxygen react with fats and break them down into compounds that smell like old nuts, crayons or paint. Unsaturated fats, the type common in seed and nut oils, turn rancid more quickly than saturated fats such as butter. A knife that carries crumbs or moisture into the tub can also give mold a foothold on butters and spreads.

What is the source for these storage times?
They come from USDA FoodKeeper, the food storage database run by the USDA Food Safety and Inspection Service (FSIS). We last checked this page against the current FoodKeeper release.
What temperature is best for storing salted sunflower seeds in the shell?
Set the fridge to 4°C (40°F) or below and the freezer to -18°C (0°F). The dial on a lot of fridges is optimistic and the real temperature runs higher, so a cheap appliance thermometer is money well spent.

What should I store salted sunflower seeds in the shell in?
Use a dark, airtight container kept away from heat and light. You want to block air and moisture, keep smells from traveling to other food, and be able to tell at a glance how old the food is. Jot the date on the lid or on a label so there is never any guesswork about its age.
Is the fridge door a good spot for salted sunflower seeds in the shell?
It does not need the fridge; a dark, dry, cool cupboard suits it best.
Can you refreeze salted sunflower seeds in the shell?
Yes, but only when they defrosted in the refrigerator and have not sat out at room temperature. Anything defrosted in the microwave or a cold-water bath needs to be cooked before it goes back into the freezer. Quality drops a little with every freeze-and-thaw round, so freeze in portions you'll use in one go.
Does freezing kill bacteria in salted sunflower seeds in the shell?
No. At -18°C (0°F), bacteria stop multiplying, but they aren't killed off. Once salted sunflower seeds in the shell thaw, any bacteria that were there wake up again, so defrost in the fridge and, where relevant, bring it up to a safe temperature when you cook or reheat it.
If salted sunflower seeds in the shell smell okay but are beyond the storage time, are they still safe?
With a low-risk food such as salted sunflower seeds in the shell, going beyond the storage time generally affects quality rather than safety. Look for mold, sniff for off odors and notice any strange taste, and get rid of them if anything seems wrong.
